Roofers Toms River installs and repairs flat roofs on additions, porches, garages and commercial buildings across Ocean County, NJ. We work with EPDM rubber, TPO and modified bitumen, fix ponding water, and rebuild the flashing where most flat roof leaks begin. A flat roof replacement typically costs $6,500 to $13,000.
Flat roof systems we install
- EPDM rubber: a flexible single-ply membrane, a common choice for additions and porch roofs.
- TPO: a white, heat-welded membrane that reflects summer heat, popular on commercial buildings.
- Modified bitumen: layered asphalt-based sheets for a traditional, durable flat roof.
Common flat roof problems
- Ponding water that sits for 48 hours or more after rain
- Seam separation on aging membranes
- Parapet and wall flashing failure, the top source of flat roof leaks
- Clogged drains that back water up onto the roof
- Punctures from foot traffic or HVAC service
Coastal storms speed all of these up. A flat roof that drains poorly will fail years before one that sheds water properly.
Flat roof repair
For roofs with life left, we patch punctures, re-seam loose sections, rebuild flashing at parapets and clear drains. Small repairs are often a few hundred dollars. See roof leak repair for how we trace hard-to-find leaks.
Flat roof replacement
- Tear off the old roof down to the deck.
- Replace any rotted decking.
- Add tapered insulation where needed so water flows to drains.
- Install the new membrane with sealed or welded seams.
- Rebuild flashing at walls, parapets and penetrations.
Flat roofs on Shore homes
Many Toms River and Beachwood homes have a low-slope porch or addition roof that was built with the wrong material for its slope, which is why it ponds and leaks. Switching to a proper membrane, with the right pitch built in, solves the problem for good.
Where we work on flat roofs
We handle flat roofs throughout Toms River and in Beachwood, Lakewood and Pine Beach. We also install flat roofs on commercial buildings.
Flat roof questions
How long does a flat roof last here?
A well-installed EPDM or TPO roof usually lasts 15 to 20 years, depending on drainage and foot traffic.
Which flat roof material is best?
EPDM is common on residential additions; TPO suits owners who want a reflective, white roof. We recommend based on your roof’s drainage and use.
Is standing water on my flat roof normal?
Small puddles that dry within a day or two are common. Water that stays longer shortens roof life and should be corrected.
